1905 (MCMV) was a common year starting on Sunday (dominical letter A) of the Gregorian calendar and a common year starting on Saturday (dominical letter B) of the Julian calendar, the 1905th year of the Common Era (CE) and Anno Domini (AD) designations, the 905th year of the 2nd millennium, the 5th year of the 20th century, and the 6th year of the 1900s decade. As of the start of 1905, the Gregorian calendar was 13 days ahead of the Julian calendar, which remained in localized use until 1923.

As the second year of the massive Russo-Japanese War began, more than 100,000 died in the largest world battles of that era, and the war chaos lead to a revolution against the Tsar. (Shostakovich's 11th Symphony is subtitled "The Year 1905" to commemorate this.) Canada and the U.S. expanded west, with the Alberta and Saskatchewan provinces and the founding of Las Vegas. 1905 is also the annus mirabilis of Albert Einstein, who published papers which lay the foundations for quantum physics, introduced the special theory of relativity, explained Brownian motion, and established mass–energy equivalence.
